This blog is filled with tons of information for Kindle owners. The tips for using the Kindle are generally broken down by the type of Kindle (One, Two, or DX) so that any Kindle owner will find useful information.
There are also posts pertaining to Kindle in the news, updates on Amazon's policies, etc. You might even find a book you like or a freebie announced.
My favorite posts are the humor ones. They are all original `jokes' written by Mr. Calvin. They are also all directly Kindle related.
Mr. Calvin obviously does a lot of research to post statistics (along with graphs) on his blog. I'm impressed with the amount of information he keeps up with.
The writing style is excellent for the content. The language is clear and concise.
Timeliness: 5 Stars
There is at least one post a day, which appears to be at about the same time every day.
"Extra" posts are thrown in for time-relevant news.
Online Version: 5 Stars

The online version of this blog is exactly what you would expect of a blog specifically designed for the Kindle. There are some extra helpful links, archives, etc., so it's worth a visit now and then. Otherwise, your Kindle Subscription gets you everything.

Both are of professional quality.
